This recording has undergone so much noise reduction that it sounds "over-processed." I know the old discs can be noisy but I would prefer a little hiss and scratches over such a tinny sound.
Also, the transfer was done in one big file, with gaps between the sides. Really jarring.
It's a bit difficult to evaluate the performance given the heavy noise processing. I would probably opt for the Rubinstein recording that's on Archive instead. The William Kapell performance remains my favorite vintage recording of the concerto, but it's not on Archive.
